ABSTRACT

Novel partially fluorinated alkenes having the Formula: ##STR1## wherein each R is the same or different and is selected from the group consisting of CF 3 , CHF 2 , CH 2  F, and CH 3  CF 2 , and R&#39; is an alkenyl or fluoroalkenyl group having 1 to 6 carbon atoms have utility as solvents in a variety of industrial cleaning applications including cold cleaning, dry cleaning, and defluxing of printed circuit boards.

FIELD OF THE INVENTION

This invention relates to novel partially fluorinated alkenes having atertiary structure and 4 to 9 carbon atoms. These compounds are usefulin a variety of vapor degreasing, cold cleaning, and solvent cleaningapplications including defluxing and dry cleaning.

BACKGROUND OF THE INVENTION

Cold cleaning is an application where numerous solvents are used. Inmost cold cleaning applications, the soiled part is either immersed inthe fluid or wiped with rags or similar objects soaked in solvents andallowed to air dry.

In cold cleaning applications, the use of the aerosol packaging concepthas long been found to be a convenient and cost effective means ofdispensing solvents. Aerosol products utilize a propellant gas ormixture of Propellant gases, preferably in a liquified gas rather than acompressed gas state, to generate sufficient pressure to expel theactive ingredients, i.e. product concentrates such as solvents, from thecontainer upon opening of the aerosol valve. The propellants may be indirect contact with the solvent, as in most conventional aerosolsystems, or may be isolated from the solvent, as in barrier-type aerosolsystems.

Vapor degreasing and solvent cleaning with fluorocarbon based solventshave found widespread use in industry for the degreasing and otherwisecleaning of solid surfaces, especially intricate parts and difficult toremove soils.

In its simplest form, vapor degreasing or solvent cleaning consists ofexposing a room temperature object to be cleaned to the vapors of aboiling solvent. Vapors condensing on the object provide clean distilledsolvent to wash away grease or other contamination. Final evaporation ofsolvent from the object leaves behind no residue as would be the casewhere the object is simply washed in liquid solvent.

For soils which are difficult to remove, where elevated temperature isnecessary to improve the cleaning action of the solvent, or for largevolume assembly line operations where the cleaning of metal parts andassemblies must be done efficiently and quickly, the conventionaloperation of a vapor degreaser consists of immersing the Part to becleaned in a sump of boiling solvent which removes the bulk of the soil,thereafter immersing the part in a sump containing freshly distilledsolvent near room temperature, and finally exposing the part to solventvapors over the boiling sump which condense on the cleaned part. Inaddition, the part can also be sprayed with distilled solvent beforefinal rinsing.

Vapor degreasers suitable in the above-described operations are wellknown in the art. For example, Sherliker et al. in U.S. Pat. No.3,085,918 disclose such suitable vapor degreasers comprising a boilingsump, a clean sump, a water separator, and other ancillary equipment.

Chlorofluorocarbon solvents, such as trichlorotrifluoroethane, haveattained widespread use in recent years as effective, nontoxic, andnonflammable agents useful in degreasing applications and other solventcleaning applications. One isomer of trichlorotrifluoroethane is1,1,2-trichloro-1,2,2-trifluoroethane (known in the art as CFC-113).CFC-113 has a boiling point of about 47° C. and has been found to havesatisfactory solvent power for greases, oils, waxes and the like. It hastherefore found widespread use for cleaning electric motors,compressors, heavy metal parts, delicate precision metal parts, printedcircuit boards, gyroscopes, guidance systems, aerospace and missilehardware, aluminum parts and the like.

Another commonly used solvent is chloroform (known in the art as HCC-20)which has a boiling point of about 63° C. Perchloroethylene is acommonly used dry cleaning and vapor degreasing solvent which has aboiling point of about 121° C. These compounds are disadvantageous foruse as solvents because they are toxic; also, chloroform causes liverdamage when inhaled in excess.

Although chlorine is known to contribute to the solvency capability of acompound, fully halogenated chlorofluorocarbons and hydrochlorocarbonsare suspected of causing environmental problems in connection with theearth's protective ozone layer. Thus, the art is seeking new compoundswhich do not contribute to environmental problems but yet provide thesolvency properties of CFC-113. From an environmental standpoint,partially fluorinated alkenes are of interest because they areconsidered to be stratospherically safe substitutes for the currentlyused fully halogenated chlorofluorocarbons.

It is an object of this invention to provide novel partially fluorinatedalkenes which are liquid at room temperature and which are useful assolvents for use in vapor degreasing, cold cleaning, and other solventcleaning applications including defluxing applications and dry cleaning.

Another object of the invention is to provide novel environmentallyacceptable solvents for use in the aforementioned applications.

Other objects and advantages of the invention will become apparent fromthe following description.
